A recent headline from Statistics Canada found that the income gap – defined as the difference between the disposable income shares of the richest 40% and the poorest 40% of households – reached a record high in early 2025.
However, little attention has been paid to the main driver of this recent spike – the increasing concentration of income derived from wealth.
In 2024, according to the same Statistics Canada data, two thirds of all the income generated from wealth – that is, income in the form of dividends from stock ownership, interest from bonds, capital gains from business and real estate sales, as opposed to from working – was collected by the richest 20% of households, up from only 56.2% in 1999. In just the last two years, the average income from wealth of the top 20% increased by 37%.
This problem is concentrated among the very highest earners. Other data from Statistics Canada shows that, for the top 1%, the proportion of their income that comes from working has declined to 44.3% in 2022 (the most recent year with available data) from 54.1% in 1999. For the top 0.01%, who collected on average $11.6 million in 2022, the proportion of income from working has declined even further, to 28.7% in 2022 down from 54.1% in 1999.
Income from wealth has become increasingly concentrated among a lucky few. This mirrors Canada’s rising wealth inequality – according to the Parliamentary Budget Officer, the top 1%’s share of wealth increased to 24.3% in 2021 from 19.8% in 1999. This means there were 161,700 families with at least $7.3 million in wealth in 2021.
Thomas Piketty’s book, Capital in the Twenty-First Century, rose to fame for highlighting this problem a decade ago – without careful attention to the issue, wealth inequality can continue to accelerate in capitalist economies. Unfortunately, instead of helping to combat the problem, our tax system contributes to it. Because of tax breaks for capital gains and dividends, tax rates on income derived from wealth are lower than those on income derived from working.
Imagine an Ontario-based CEO who earns $13.2 million a year, which was the average pay of the 100 highest paid CEOs in Canada in 2023 and happens to be 210 times the average income of a worker. Most of their pay comes in the form of stock options and shares in their company, which is retained as wealth. During their tenure working as CEO, most of their income would be subject to the top marginal tax rate on employment income of 53.5%. Although clever tax planning could allow CEOs to avoid some of this tax, compensation through shares and stock options above $200,000 (thanks to a legislative change in 2021) are fully taxable. But after retiring at the end of 10 years as an extremely highly paid CEO, assuming they spent one million dollars annually, they could have accumulated over $75 million in wealth held in shares of their own company plus other passive investments.
A modest estimate of the retiree’s returns would be 2% of their wealth in dividends and 4% of their wealth in capital gains. This is over $4.5 million in annual income that would be generated without any work, and would be taxed at only 31% because of the generous tax breaks for dividends and capital gains. Because Canada has no wealth or inheritance tax, this passive income could continue indefinitely, even being passed on to their children.
And the CEO’s taxes would likely be even lower in practice. They could avoid capital gains taxes for years if they do not sell their assets. They can use tax-free savings accounts, which are only fully exploited by high earners, to shield some of their income from wealth from taxes. They could enlist highly –paid lawyers to help them avoid their taxes through the use of tax havens. Because of all these loopholes, the top 1% of income earners, who earn most of their income from wealth, pay only 23.6% of their income in taxes, while middle-earning Canadians pay over 43% of their income in taxes. Reminiscent of the gilded age, this system has created a new class of plutocrats that earn income from wealth extraction instead of wealth generation.
Rather than using the tax system to prevent wealth concentration, as Piketty recommended, our current tax system promotes wealth concentration – those who earn income from wealth have more income left over after taxes, allowing them to accumulate wealth more quickly than others. Even some of the wealthy themselves are now calling to be taxed more, recognizing the unfairness inherent in the current regime and the related systemic risks to social cohesion, democratic stability and economic growth that emerge in situations of deep inequality.
South of the border we are witnessing the consequences of runaway wealth inequality – billionaires use their media conglomerates to get political favours, exploit the instruments of the state to enrich themselves, and, increasingly, secure political office.
All of these trends are leading to the erosion of democracy and public policy that advances the interests of billionaires at the expense of everyone else. If Canada does not rebalance our tax system to prioritize work over wealth, we may soon find ourselves on the same path. A tax system that promotes efficiency and fairness will reinforce our democracy and protect our sovereignty in the face of the challenges represented by Trump.

Trump pumps private equity with 401k changes | Breaking Points podcast
Breaking Points podcast correspondent James Li sits down with corporate lawyer, economic analyst and SCP Fellow Rachel Wasserman to discuss Trump's executive order opening up 401k plans to private equity. Trends show that with rising interest rates and frozen exit markets, the private equity investment model could be under serious stress. So, what are the implications of making this type of investment available to retail investors and their retirement plans? Rachel walks James through how private equity works, what's so dangerous about the buyout-PE model and who might get left holding the bag.
The problem with GDP per capita | West of Centre on CBC
New research by economist and SCP Fellow Gillian Petit estimates what Canada’s GDP per capita would have been over the past decade if Canada had kept our temporary resident numbers stable. On CBC political podcast West of Centre, host Rob Brown asks Petit to dissect the metric politicians love to wield. GDP measures total output, while GDP per capita divides that sum by the population. She explains that the simple math offers an easy snapshot, but can mislead when used alone. For a true read on prosperity, Petit argues Canada needs a broader economic dashboard that weighs productivity, fairness and long term well being.
Blame the denominator, not the economy
Over the last couple of years, there have been countless articles warning of Canada’s poor economic performance. The mic drop has increasingly been Canada’s poor performance relative to peer countries on “GDP per capita,” with growth rankings used to draw a variety of sweeping, negative conclusions about Canada’s economy. SCP CEO Matthew Mendelsohn and Policy Director Dan Skilleter draw on economist and SCP Fellow Dr. Gillian Petit's new research to explain why GDP per capita is a deeply flawed measurement for evaluating rich countries - and is easily influenced by a variety of factors having little to do with economic performance or economic well-being.
